Chilled Water and Condenser Filtration System Enhancing Efficiency & Water Quality
Conventional building central cooling plants, comprising water-cooled chillers, air handling units (AHUs), cooling towers, and pumps, often suffer fouling issues caused by accumulation of suspended solids in the micron range, such as rust and corrosion scale, as well as dissolved minerals within the chilled water closed loop system. Over time, these impurities clog strainers and nozzles, foul heat exchangers, and impair heat transfer efficiency, resulting in turbid water and reduced cooling performance. In condenser water open loop systems, untreated or ineffectively treated water further cause abrasion and leakage in condenser copper tubes, leading to system downtime and costly maintenance.
To address these challenges, this invention introduces an effective and energy-efficient cleaning and filtration system that continuously filters blackish and rusty chilled water, returning cleaner and clearer water to the chilled water closed loop system. By leveraging existing water pressure without requiring an external pump or additional electricity, the system restores water clarity and operational efficiency, leading to:
Reduced cooling energy consumption
Enhanced occupant comfort and wellbeing
Significant reduction in water usage for system cleaning
Lower operational costs, carbon footprint, and emissions
Alignment with the “Go 25°C” National Movement led by the Singapore Green Building Council (SGBC)
The technology owner seeks collaboration with building owners, facility managers, main contractors, chiller and cooling tower manufacturers and suppliers, and energy service companies (ESCOs) to explore integration in new developments and retrofit applications.
